WILLIAM MILLER JONES, 0F TARENTU'M, PENNSYLVANIA.

To all whom "it may concern.-

Be it known that I, WILLIAM MILLER J ONES, citizen of the United States,residing at Tarentum, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inGages, of which the following is a specification.

My invention relates to improvements in wood scribing gages of the classused in laying ofl carpentry and cabinet construction and is especiallyadaptable for scribing the seats of shutter and door hinges and butts.

The objects of my invention are,- -l, to provide an accurate, compactand durable tool for the purposes named; 2, to provide a gage that iseasily adjustable; 3, to provide a gage having easily interchangeableparts. I attain these objects by the mechanism illustrated in theaccompanying drawings in which,

Figure 1 is a longitudinal view of one of the working faces, Fig. 2 is alongitudinal view of the opposite working face, Fig. 2 is a reversedview of a disk showing a roughed surface. Fig. 3 is an end view having aportion broken away on the line 83 of Fig. 1. Fig. 4 is a transversesection taken on the line 44 of Fig. 1. Fig. 5 is a section on the line55 of Fig. 3. Fig. 6 is a detail in perspective of a scribing member.

Referring to the drawings in which simi lar numerals designate similarparts throughout, 1 is the body portion, comprising a wooden block 2,the face plates 3 and the internally disposed nuts 1- and 5. The plates3 are fixedly united with the block 2 by means of the screws, one ofwhich is designated by the numeral 6. The nuts 4: and 5 are insertedinto the body by means of wooden pins 7 and 8, which are pierced toreceive the nuts, which when positioned therein are fitted together withthe pins into the holes 9 and 10, provided for the reception thereof.The object of thus embedding the nuts is to provide substantial bearingsfor the thumb screws, 11 and 12, whose function is to hold the majorgage beam 13, and the minor gage beam 14 respectively to their setpositions.

Fitted to an end of the beam 13, is the scribing member 15 which isembedded flush with the end of the'beam with the exception of thescribing point 15, which is off-set slightly. Secured to one side of thebeam 13, is a bearing plate 17, which is engaged by the thumb screw 11.A metallic disk 16- is Specification oftLetter s Patent.

[ disposed upon one end of the beam 14, and constltutes a scrlblngmember, over-hanging the perimeter of one end of the shaft sufficientlyto make a clearly visible impression upon the surface to be scribed.This disk is used to scribe the surface or butt.

An advantage of a circular scribing member is that a cutting edge isalways presented to the work and that new cutting edges are obtainableby rotating the shaft 14.

In fitting hinges to doors and jambs when the door stops are adjustableand not rabbeted into the solid j amb, the offset point of scribingmember 15 on the major beam 13, is employed for scribing the hinge seatin both door and jamb for no clearance is es sential, the stops can beplaced to suit the door.

In cases where the stops are rabbeted into the solid jamb and cannot beadjusted then the fiush point of scribing member 15 is employed on thedoor and the offset point on the j amb. This allows for a slightclearance of door and stop. The flush point of scribing member 15 isused only in cases where the stops are rabbeted into the solid jamb andcannot be adjusted and no clearance allowed for the door to swing freewhen held in place. The special object and design of this feature is togage the thickness of hinges, and then to scribe according to that gagefor seating the hinge thus gaged. In gaging the thickness of the hingeit is laid fiat upon the face plate 3, adjacent to the scribing disk,which is set with its scribing edge flush with the top face of thehinge. The back surface of the disk 16 is' roughed as shown at 18, Fig.2*, so as to prevent it from turning when scribing.

Having described my inventionl claim and desire to secure byLetters'Patent:

1. The combination in a wood scribing gage of a block having disposedtherethrough a plurality of beams, thumb screws for holding the beams totheir set positions, fixedly and internally disposed nuts engaging thethumb screws, a scribing disk attached to one of the beams, a doublepointed scribing member embedded into an end face of the other beam, oneof the scribing points being offset with the end of the beam, for thepurpose stated and substantially as specified 2. The combination in awood scribing gage of a metal faced block having a major beamtherethrough carrying at one end a double pointed scribing member oflsetwith In testimony whereof I affix my signature, the end of saicll beam,a minor beam disposed in presence of tWo Witnesses.
